Procedure

Sodium borohydride (2 mg) is added to an ethanol (1 mL) solution of (E)-3-(3-formyl-4-(1H-imidazol-1-yl)phenyl)-N-indan-1-ylacrylamide (17 mg) obtained in Example 437 and the reaction mixture was agitated for 30 minutes at room temperature. After the reaction solution was concentrated under reduced pressure, water and ethyl acetate were added to the residue, and the organic layer was partitioned. The organic layer was washed with a saturated saline solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (Carrier: Chromatorex™ NH, elution solvent: methanol-ethyl acetate system), and 1.8 mg of the title compound was obtained.
